Welcome! This website serves to show recent work. For my writing, please visit my blog. For my official bio, please see my LinkedIn page. I currently work with Amory Lovins, founder of the Rocky Mountain Institute. We drive a more sustainable future, by showing companies that sustainable operations almost always equal more profit, and by helping companies to re-engineer their buildings and industrial processes. Working in such a role, it should come as no surprise that I enjoy designing and making things. My choice to study engineering was somewhat fortuitous—most of my creations in high school were artistic, not technical—but I became exposed and excited about hands-on engineering as I moved from Delft to ETH Zurich and later to MIT. My fellow students in Zurich and Boston exposed me to their technical side projects and the joy that flows from making physical objects. I was able to build skills in mechanical engineering and software development with Nest, FirstFuel Software, and Infosys' Green Buildings Practice. As much as engineering and problem solving, I enjoy convening people and building environments in which others can create and learn. I first experienced this when running a catering company with undergrad engineering friends in Delft. I later gathered young entrepreneurs as the founder of the Dutch chapter of the Kairos Society; investors as the founder of Cool Schools, a solar PV financing initiative; and students as one of the founding team of Spokes America. Through these experiences I have learned that I love to bring a project to realization, to tell a story, and to bring excitement. Yet my inspiration comes not primarily from successful entrepreneurs. I am inspired mostly by people who look(ed) at the world differently: Buckminster Fuller, Carl Sagan, Richard Feynman, Benjamin Franklin. I try regularly to ask myself: how could this be done differently?, as you will likely observe if you read my blog. I have felt the tremendous human energy that is released when people work for a cause beyond their ego, a cause in which they truly believe. My dream for the next one, ten, fifty or one hundred years—however many I may have—is to build teams that create products and services that matter: that help us be kinder humans that make better choices; live in more beautiful, productive, and safe environments; and connect us with everything around us.
